you do /chanserv akick add nick for example.
And nick is automatically kicked out of the channel... only one with enough level can unackick him... or himself, if he has the the level to do it.
It's not ban, it's really an automatic kick.
If this is placed on a bot, no chance!
There I ask for the akick remover.
/chanserv akick del (botnick)
